I had some experience with 3D printing in the school where I was running a robotics club. As luck would have it I got an internship in a startup called EDM machinery, that was developing a 3D printer, their main business was designing and building custom CNC Routers.
I took one of their prototype frames and started building on that.The frame was inspired from prusa and mendel style printers and I designed my first 3D printer around that. The frame had quite beefy Hiwin linear rails which were left overs from CNC router build.
RAMBo v1.3. The RAMBo board is an all in one 3D printer motherboard. It is a full remix of RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB. For the hotend I ordered an E3D Chimera dual hotend so I could use two different materials. After I completed my initial design I was eager to start building it.
I was going to house the printer board and power supply on the bottom of the printer, but after I put it together, the Y axis was moving quite the mass and the intersia caused visible layer shifts in the print. So I didn’t finish the printer and that led me to go back to the CAD to redesign the Y axis, but ended up redesigning the whole printer. And after some thinkering i decided to build a Core XY printer instead. I have another post entirely for that project –> ZRK-MEGA.
I got into 3d printing in the school where I worked at, we needed a 3D printer for robotics class/workshop and after a little bit
